RUNAMUCK Posted December 7, 2009 Share Posted December 7, 2009 If you want the good oil RT, be talking to Wyane Martin in Waller tce. He's VERY helpful. There has been a book released about modifying cars by the LVVTA, called the hobby car technical manual. It tells you everything about doing things the right way. But it costs a fucking fortune though. The basic gist of ground cleance rules pertain more to if you get a flat tyre the chassis cant hit the road and cause you to roll. A zhorst/skirt/sump will be able to deform ect which while it's still a bad buzz isnt going to result in the car tipping over onto it's roof. (Which would be even more of a bad buzz) Quote Link to comment Share on other sites More sharing options...
Hemi Posted December 7, 2009 Share Posted December 7, 2009 shit i put my limit at maybe 70mm lower in the 910 before i get sketchy the rear swaybar mounts hit on the rougher roads and the exhaust hits even on medium roads . and they aint that low . driving the 910 at cutspring height (pre 2009 spec) was terrible Quote Link to comment Share on other sites More sharing options...
Yowzer Posted December 7, 2009 Share Posted December 7, 2009 Wouldn't be keen on anything daily lower then 100mm tbh, unless it has the ability to lift itself up again. NZ roads / my driveway are way too shit to cope with Something like a road legal track car however, I would drop as far as it could go Quote Link to comment Share on other sites More sharing options...
Simon Posted December 7, 2009 Share Posted December 7, 2009 Im going to try cert my corona at 50mm from the cross member but probably lift it a bit after. And yeah, don't know how Im going to get out of my drive way. Might just move from home into a flat that I can get in the drive way. Quote Link to comment Share on other sites More sharing options...
CaMpylobacter Posted December 7, 2009 Share Posted December 7, 2009 I'd roll something down to about 70 or 80mm tbh. short wheelbase is where it's at. long wheelbase cars are a total cunt if you want to drive into driveways and shit. I get beached about half way down my front doors, smooshing the shit out of my exhaust, and smack the towbar all the time. i'm about 100mm at front crossmember.

Brock-Lee Posted December 7, 2009 Share Posted December 7, 2009 logans skyline is at 60mm to chassis. It is a easy daily. takes a fucken decent speedbump to get beached and dont scrape 95% of the time. Just go slow and put up with it. shit dont look good high Quote Link to comment Share on other sites More sharing options...
Simon Posted December 7, 2009 Share Posted December 7, 2009 I might build a small bash plate 4x4 spec. So it just bounces off and over things like manholes rather than hook into them on the edge of the cross member. Quote Link to comment Share on other sites More sharing options...

Leebo3 Posted December 7, 2009 Share Posted December 7, 2009 This is a handy thread, should sticky it or put it in a good thread bank. Obvisously, if your going for a cert you should bone your car right out (safely) and get it done for that height, if not the most practical lift it a tad, but then you always have the lowness issue covered.

Testament Posted December 7, 2009 Share Posted December 7, 2009 you get +/- 5% measured from wheel center to top of the guard I think? so something like +/- 10mm for certed suspension setups. you must be able to get something on certs for a range of heights though, because what about cars with airbags/hydraulics?

Dont think the cop would mind if you were higher than you were legally were allowed to go. But in saying that, cops will fine you for anything.

Sparkle Posted December 7, 2009 Share Posted December 7, 2009 spraks bmw sump was wwaaaaayyyy forward of the front axle + cast aluminium. was aws/dumb. he smacked it on on eof those dumb judder bars at the terrace end end of broadway ftl 80mm off the floor with above specs ftpainintheass. Ute is about 115 from lowest anythin to the floor and is perfect for daily's, especially Palmerston North's crappy roads, judder bars etc. So do suspension components count as measured from? Or just chassis? Quote Link to comment Share on other sites More sharing options...
CaMpylobacter Posted December 7, 2009 Share Posted December 7, 2009 well when i skim read that bit before it reckoned that outer balljoints are meant to be at least 100mm off the flo' too, thus, lowering block lowering may push lower spring seats and shock mount elow 100mm? you've got a theoretical 148mmsidewall so as long as it's not past the rim then you should be millions of mm away from the ground in that respect.....

mikuni Posted December 7, 2009 Share Posted December 7, 2009 It specifically says outter ball joints aren't applicable, along with brake backing plates so I'm sure any of the suspension components that move with the wheel would be the same.

Prof Schnorz Posted December 7, 2009 Share Posted December 7, 2009 The cress is certed at 40mm to chassis rail, still an ok daily but not recommended unless your good with angles I have had a cop try to ram his notebook under, sayin below 100mm is illegal regardless of cert , followed up with "but im no engineer" Generally most dont actually know how the cert is measured. Usually i tell them what the numbers mean just to sound like a good cunt so they let me off quicker... Never had a fine but been pulled up by every cop in town Quote Link to comment Share on other sites More sharing options...

Jase Posted December 7, 2009 Share Posted December 7, 2009 i'm rolling probably decent daily height on 14's but what is the rule regarding modifying x members and bumpstop towers ie mod x for beams mounts to use toyota og parts and towers for way more low with travel still, ie can run a softer spring but still have fully laden with out hitting bumps Quote Link to comment Share on other sites More sharing options...
